WhatsApp is dropping support for older smartphones that aren’t compatible with its latest features. At least one generation of iPhone, alongside older versions of Android and Windows Phone, will no longer be able to use the service at the end of the year.

At this point, there have been eight iPhones, and with the exception of this year’s iPhone 5c, each has a faster chip and more all around chutzpah than the model that precedes it. You’d naturally think, then, that if you lined them all up in a row and ran a speed test on them, each successive model would accomplish tasks faster than the model that precedes it. But as this video proves, the reality is more complicated than that.

Shazam, Shazam Encore, and Shazam RED for iOS have today been updated with a number of new features and improvements. In addition to faster recognition on older iOS devices, and improved recognition in “difficult” environments, the release also brings Twitter previews and new TV experiences for those in the United States.

Apple has confirmed to CNBC that a new iPhone trade-in program will be available in Apple Stores across the United States today — less than two weeks before the Cupertino company is set to announce the iPhone 5S and iPhone 5C.

Customers will be able to exchange their old Apple smartphone for a gift card, which can then be redeemed against a new device with a new two-year contract.

The low-cost “iPhone 5C” hasn’t been announced yet, but it already feels like we’re pretty familiar with it — mostly because we’ve seen so many pictures of its plastic rear shell. But most of those — the high quality ones, at least — have included the white model.

A new hands-on video that has surfaced today shows off the yellow model in all its glory.
